  • Heavy duty (6000 psi high pressure) series: 1/2″, 3/4″, 1″, 1.1/4″, 1.1/2″, 1.3/4″, 2″

Working pressure:

SAE weld flanges can be used for applications under pressure from 35 bar to 415 bar depends on the sizes and the grades of the bolts used. Bolts are in grade 10.9 or grade 8.8.

Working temperature:

The working temperature range for Younglee’s most popular SAE weld flanges is -20℃ to +90 ℃, but by changing the materials of the O-ring, seals, our products can be suitable for higher and lower temperatures.
